FEED-ROLL FOR PLANlNG-MACHlNES.

.SPECIFICATION forming part of Letters Patent No. 269,118, dated December 1.2, 1882.

Application inea May 22, 1882. (No model.)

l'o all whom it may concern Beit known that I, THOMAS H. RODENBOH, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented an I mprovetnentin Feed-Rollsfor Wood-Working Machines, ot'whieh the following is a specification.

The object of my invention is to construct rubber-surfaced feed-rolls which can be readily applied to or removed from the feed-shafts of wood-planing machines, and this object I at tain in the manner which I will proceed to describe, reference being had to the accom pu nying drawings, in which- Figure 1 is a side View, partly in section,of my improved feed-roller; Fig. 2, a View of the parts detached from each other, and Fig. 3 a transverse section of the feed-roller.

A 'represents part of a feed-shaft of a Woodplaniugmachine, a portion of the table or bed and'the rotating cutting-tool being shown by 'dotted lines. i

The roller consists ot' a metal sleeve, B, and a tube, el, of rubber, titted tightly to the sleeve and coniined thereto by and between a nut, b,

adapted to the threaded end of the sleeve', and

a permanent collar, a', at the opposite end' of the same.

It should be explained that the exterior of the'sleeve is made cylindrically true and plain for the reception and tight ttting of the short rubber tube, and that when the nut is screwed tight the rubber will so cling to the sleeve that it cannot be displaced by the torsion to which the roller is subjectecL The feed-roller is complete Within itself, the

rubber tube being fitted and tightened in its place on the sleeve, and properly trued, so that the roller can be applied to the shaft in the same manner as au ordinary wheelor pulley is detachably secured to ashat't. The thread e on the sleeve and the correspending thread 'iu the nut should be right or left handed,aceording to thedirection in which the roller has to turn, the direction of the thread being such that' torsion on the rubber shall not have a tendency to nnserew the nut.

I am aware that in the manufacture ot' rollers for clothes-wringers long rubber tubes have been applied to shafts; but especial pro' vision was made on the latter to prevent the displacement of the rubberby torsion, Whereas this object is attained in my invention partly by thetight tting of the short rubber tube to a plain sleeve and partly by a slight contraction of the tube endWise, which causes it to cling tightly to t-he sleeve.

j I claim us my invention- The within-described feedroller, in which the metal sleeve B, having a bore adapted to a feedshaft made cylindrically true externally, and provided with a. collar, a, and-nut d, is combined` with `a short rubber tnbe fitted tightly to the sleeve and confined thereto by end pressure imparted by the nut, as set forth.

In testimony whereof l have signed myname to this specitication in the presence of two subscribin g Witnesses.
